[0002] At present, before a medical linear accelerator can treat a patient, it is necessary to move the patient's lesion to the isocenter. This isocenter is indicated by the laser beams emitted by three laser lamps at different positions converging at one point, and the position of this isocenter is fixed. The patient lies on the treatment bed, and the medical staff marks the location of the patient's lesion, lifts, translates, and rotates the treatment bed. After the lesion is moved to the isocenter, the beam treatment conditions are met.

[0010] Specifically, the determining whether the duration of the user pressing the start button is greater than or equal to the motion rule conversion threshold, and determining whether to control the treatment bed to move according to the uniform motion rule according to the determination result, includes: If the duration of the user pressing the start button is greater than or equal to the motion rule conversion threshold, the treatment bed is controlled to move according to the uniform motion rule; If the duration of the user pressing the start button is less than the motion rule conversion threshold, the treatment bed is controlled to continue moving with the variable speed motion rule.

[0011] Specifically, the speed in the uniform motion rule is greater than or equal to the maximum speed under the variable speed rule.

[0012] Specifically, the variable speed movement rule is: increasing the current speed linearly or increasing the current treatment bed moving speed nonlinearly.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-6 The present invention provides a rapid alignment device for a lesion target, comprising: A treatment bed motion shaft, wherein the treatment bed motion shaft is used to rotate under the drive of the treatment bed motor, thereby controlling the movement of the treatment bed; The treatment bed motor is used to drive the treatment bed motion axis to rotate at a corresponding rotation speed under the control of the control module; A start button, which is used to obtain a start signal input by a user; The control module is used to record the duration of the input start signal and control the speed of the current treatment bed movement according to the duration.

[0022] Specifically, recording the duration of the input start signal and controlling the current movement speed of the treatment bed according to the duration includes: According to the start signal input by the user, the motor of the treatment bed is controlled to start; it is used to use a timer set in the control module to record the duration of the user pressing the start button, and according to the duration of pressing the start button, the movement speed of the treatment bed is changed according to the preset rules.

[0023] Control module, when there is no start signal input from the start button, the record of the start signal duration is cleared and set to 0.

[0024] It can be understood that the present invention provides a rapid alignment device for a lesion target 1 and a control method thereof, and a treatment bed, by judging whether a start signal input by a user is obtained; if so, controlling the motor of the treatment bed to start; using a timer set in the control module to record the duration of the user pressing the start button; and changing the movement speed of the treatment bed according to a preset rule according to the duration of the user pressing the start button. It is achieved that not only the treatment bed can be moved at high speed to the vicinity of the isocenter at a distance from the center point of the laser lamp 2, but also the lesion target can be aligned with the laser center point at a low speed and smoothly near the isocenter, which greatly reduces the alignment time before treatment.

[0025] Please continue reading Figure 1-5 The present invention provides another embodiment, which provides a control method for a rapid alignment device for a lesion target. The control method for the rapid alignment device for a lesion target includes: S100, determining whether a start signal input by a user is obtained; if so, controlling the motor of the treatment bed to start.

[0026] Specifically, the method further includes: If a start signal input by the user is obtained, the treatment bed is controlled to move at a variable speed rule.

[0027] Specifically, the method further includes: If the start signal input by the user is not obtained, the treatment bed motor is controlled not to rotate.

[0028] It should be noted that the step before step S100 includes: The variable speed motion rules, motion rule conversion thresholds, and uniform speed motion rules are pre-set in the control module.

[0029] It can be understood that the variable speed motion rule, motion rule conversion threshold, and uniform speed motion rule can be set according to actual needs. The present invention does not limit the specific values ​​of the above parameters, as long as it is applicable to the control method of the rapid alignment device of the lesion target proposed in the present invention.

[0030] In a preferred embodiment of the present invention, refer to Figure 3 , set the motion rule conversion threshold to 3s. When the start button is pressed for less than 3s, the speed of the treatment bed is controlled according to the variable speed motion rule with fixed acceleration and gradually increasing motion speed. Such variable speed motion rule is mainly used when the target point of the treatment bed is close to the center position. By controlling the duration of the start button being pressed, select low speed and lower speed for alignment to avoid overtravel when the start button is pressed and the need to adjust back and forth. When the start button is pressed for greater than or equal to 3s, the movement of the treatment bed is controlled according to the fixed uniform motion rule. For example, when the start button is pressed for greater than or equal to 3s, the treatment bed moves at 10mm / s. Of course, the speed of uniform motion here should be greater than or equal to the maximum motion speed under the variable speed motion rule. When the speed of uniform motion should be greater than the maximum motion speed under the variable speed motion rule, see Figure 3 In the middle, line segment ① and line segment ④; when the speed of uniform motion is equal to the maximum speed under the variable speed motion rule, see Figure 3 The above control method is obtained by the technicians of the present invention through a large number of tests, and can easily align the lesion target with the laser center point, greatly reducing the alignment time before treatment, and further improving the usability of the present invention.

[0031] Of course, in some embodiments, the variable speed motion rule can also be controlled in sections, see Figure 4 ,For example: The variable speed motion rule is specifically: presetting the first preset speed segment, the first preset threshold, the second preset speed segment, the second preset threshold, the third preset speed segment, and the third preset threshold in the control module. The third preset threshold is the speed rule conversion threshold, and the uniform speed motion rule corresponds to the fourth preset speed segment.

[0032] It can be understood that the first preset speed, the second preset speed, the third preset speed, the fourth preset speed, the first preset threshold, the second preset threshold, and the third preset threshold can be set according to actual needs. The present invention does not limit the specific values ​​of the above parameters, as long as it is applicable to the control method of the rapid alignment device of the lesion target proposed in the present invention.

[0033] In a preferred embodiment of the present invention, refer to Figure 4 , the first preset threshold is preferably 1 second, the second preset threshold is preferably 2 seconds, and the third preset threshold is preferably 3 seconds. The second preset threshold is equivalent to the motion rule conversion threshold in the previous embodiment. The first preset speed is preferably 0.25 mm / s, the second preset speed is preferably 1 mm / s, the third preset speed is preferably 10 mm / s, and the fourth preset speed is also preferably 10 mm / s. Figure 4 , before 2s it is equivalent to the variable speed motion rule, and after 3s or more it is a fixed speed, that is, the uniform speed motion rule. The above parameters are obtained by the technicians of the present invention through a large number of tests, which can easily align the lesion target with the laser center point, greatly reducing the alignment time before treatment, and further improving the usability of the present invention. Although the button can be adjusted in place when the button is pressed for 1s or 2s, the adjustment process still requires multiple attempts.

[0034] For finer control, balancing speed and accuracy, see Figure 5-Figure 6 , attached Figure 5 -Attached Figure 6 In the figure, the transition between the first preset speed, the second preset speed, the third preset speed, and the fourth preset speed corresponding to line segment ①, line segment ②, line segment ③, and line segment ④, respectively, may include linear increase or nonlinear increase. It should be noted that the present invention is not a simple uniform motion of each segment. The idea of ​​the present invention is to perform non-uniform motion within a certain period of time, and to perform high-speed uniform motion after a certain time threshold. Before performing high-speed uniform motion, the longer the start button is pressed, the greater the speed. The nonlinear increase includes increasing the current moving speed of the treatment bed according to a preset fixed acceleration or a preset non-fixed acceleration.

[0035] It can be understood that the specific rotation speed of the treatment bed motor when the treatment bed is moved at different moving speeds can be set according to the specific step size of the treatment bed motor used by the user of the present invention. The present invention does not limit the specific rotation speed of the treatment bed motor, as long as the treatment bed can be moved at the corresponding moving speed.

[0036] S200: Using a timer disposed in the control module to record the duration of the user pressing the start button.

[0037] Specifically, controlling the treatment bed motor to stop running also includes: Clear the duration of the recording to zero.

[0038] Specifically, clearing the recorded duration time includes: Reset the timer in the control module.

[0039] S300: According to the duration of pressing the start button, the moving speed of the treatment bed is changed according to a preset rule.

[0040] Specifically, the step of changing the moving speed of the treatment bed according to a preset rule based on the duration of pressing the start button includes: If a start signal input by the user is obtained, the treatment bed is controlled to move according to a variable speed motion rule, and the speed in the variable speed motion rule increases as the duration of the start button increases.

[0041] Specifically, according to the duration of pressing the start button, the movement speed of the treatment bed is changed according to the preset rule, including: judging whether the duration of the user pressing the start button is greater than or equal to the motion rule conversion threshold, and judging whether to control the treatment bed to move according to the uniform motion rule according to the judgment result.

[0042] The step of judging whether the duration of the user pressing the start button is greater than or equal to the motion rule conversion threshold, and judging whether to control the treatment bed to move according to the uniform motion rule according to the judgment result, includes: If the duration of the user pressing the start button is greater than or equal to the motion rule conversion threshold, the treatment bed is controlled to move according to the uniform speed motion rule; if the duration of the user pressing the start button is less than the motion rule conversion threshold, the treatment bed is controlled to continue to move according to the variable speed motion rule.

[0043] Specifically, the speed in the uniform motion rule is greater than or equal to the maximum speed under the variable speed rule.

[0044] Specifically, the speed-changing motion rule includes multiple speed-changing motions, and the speed-changing motion rule is: using a method of linearly increasing the current speed or nonlinearly increasing the current treatment bed moving speed; Therefore, nonlinearly increasing the current speed includes increasing the current moving speed of the treatment bed according to a preset fixed acceleration or a preset non-fixed acceleration; The preset non-fixed acceleration is to increase the current preset fixed acceleration according to a preset change rate.

[0045] It can be understood that this patent is a speed control algorithm for the motion axis of the treatment bed. This control algorithm is to achieve that when the lesion point of the treatment bed is far away from the center point of the laser, by pressing a button, the lesion point of the treatment bed can approach the center point of the laser at high speed; near the center point of the laser, it can be fine-tuned at a low speed to align with the center point of the laser. Therefore, according to the different distances between the lesion point and the center point of the laser, the movement speed of the motion axis of the treatment bed is controlled accordingly by controlling the duration of pressing the start button. The control speed is determined by calculating the length of time the button is pressed. The longer the button is pressed, the greater the speed, achieving the purpose of high-speed movement at a long distance. At the same time, the magnitude of the speed increase increases with time, that is, the movement speed of the treatment bed is increased according to the preset acceleration; the shorter the pressing time, the lower the speed, achieving the fine-tuning alignment function near the center point.

[0046] It should be noted that the present invention provides a rapid alignment device for a lesion target 1 and a control method thereof, as well as a treatment bed, by judging whether a start signal input by a user is obtained; if so, controlling the motor of the treatment bed to start; using a timer set in a control module to record the duration of the user pressing the start button; and changing the movement speed of the treatment bed according to a preset rule according to the duration of the user pressing the start button. This achieves the goal of not only allowing the treatment bed to move at high speed to near the isocenter at a distance from the center point of the laser lamp 2, but also allowing the lesion target to be steadily aligned with the laser center point near the isocenter, greatly reducing the alignment time before treatment.

[0047] See also Figure 5 The following is a description of the workflow of the present invention through a preferred embodiment: The algorithm for the required key pressing time and motion axis relationship is as follows: When the key is pressed for less than 3 seconds, The speed is controlled by the variable speed motion rules. In this process, the speed increases with the increase of the button pressing time, and the acceleration also increases. This control mode is mainly used when the target is close to the center, such as a distance range of several mm to tens of mm. When the button is pressed for a duration greater than or equal to 3s, it is pressed. This control mode is mainly used for fast approach when the target is far from the center. Specific: When the button is pressed, the timing starts at the same time. When the timing time is less than 3 seconds, the movement speed of the treatment bed is For example, if a smaller displacement adjustment is required, it can be controlled by shortening the time the button is pressed. For example, if the pressing time is less than or equal to 1s, the speed control is If the pressing time is less than or equal to 2s, the speed is controlled within If the pressing time is less than or equal to 3s, the speed is controlled within Within.

[0048] It is used when aligning the target or isocenter at a short distance to balance the alignment time and alignment accuracy. When the timing time is greater than or equal to 3 seconds, the movement speed of the treatment bed is directly adjusted to The speed is used to move quickly, which is suitable for rapid approach at a long distance. The overall trend of speed control is that the longer the button is pressed, the faster the speed will be, and the greater the speed increase will be. When the timing time is greater than a certain value, such as 3 seconds, the speed moves at a uniform speed and does not need to be increased indefinitely. Such a speed control strategy can adapt to the adjustment needs at different distances. For example: when the target is far away from the isocenter, a long press can achieve rapid approach. When the target is close to the isocenter, the position is fine-tuned at a lower speed. In this way, different time periods correspond to different speeds and speed increase ranges. During the entire process of aligning the target with the isocenter, you can first press and hold for high-speed approach, and then press and hold for fine-tuning, so as to achieve fast and precise alignment throughout the alignment process. It can meet the user's expectations for control speed and control accuracy. Of course, the It is set by the user, for example, 1 mm / s, 2 mm / s, etc. If the user needs to increase the overall speed, just set the basic speed a little higher.

[0049] The specific algorithm formula is as follows: Where, t represents the start button pressing time (s); Indicates the moving speed of the treatment bed (mm / s); Indicates the basic speed of the treatment couch. In order to more precisely control the alignment accuracy during the final fine adjustment, the above speed control section can also be more finely segmented, for example: Please participate Figure 6 The working process of the present invention is described by way of specific examples: The treatment bed button is pressed within 1 second, and the treatment bed moves at a speed of (like Figure 5 Line segment ①) realizes low-speed alignment of the laser center point, reduces the back-and-forth adjustment time at the center point over-travel and under-travel, and meets the fine-tuning requirements near the laser center point; when the treatment bed button is pressed for more than 1 second and less than or equal to 2 seconds, the treatment bed movement speed is (like Figure 5 Line segment ②) realizes low-speed alignment of the laser center point, reducing the back-and-forth adjustment time of overtravel and undertravel at the center point; when the button is pressed for more than 2 seconds but less than 3 seconds, the movement speed of the treatment bed is (like Figure 5 Line segment ③) to achieve a faster alignment of the laser center point; when the pressing time exceeds 3 seconds, the motion axis will The laser moves at a high speed (as shown in line segment ④ in the figure) to achieve the purpose of quickly approaching the laser center point at a long distance.

[0050] It can be understood that in the above specific embodiment, when the duration of the user pressing the start button is less than the third preset threshold, the treatment bed is controlled to smoothly increase the moving speed; when the duration of the user pressing the start button is greater than or equal to the third preset threshold, the treatment bed is controlled to move at the highest moving speed, thereby enhancing the stability of the treatment bed during the movement process and improving the experience of the person receiving treatment.

[0051] Specifically, the algorithm implementation process of the present invention is as follows: The motion control of the treatment bed is realized through PLC (Programmable Controller). The button status is used as the input signal of PLC, and the button pressing timing and speed regulation function can be realized through PLC. First, the button is connected to the PLC input terminal, the timing starts when the button is pressed, and the timing stops when the button is released; write a timing program to convert the time into speed, and then output the analog value of the speed to the servo motor driver to complete the speed control function.

[0052] The hardware selection is as follows: the selected PLC model is Siemens S7-1515; without hold-type buttons; Siemens 0.5KW servo motor and matching Siemens servo driver.

[0053] The non-hold-type button is a button without a self-locking function.

[0054] The program design is as follows: Set the basic speed of the treatment bed to 1mm / s; Timing and converting time data into real data.

[0055] According to the timing time: if it is less than 3 seconds, the first control signal out1 is output; if it is greater than or equal to 3 seconds, the second control signal out2 is output; different speed settings are output according to different timings: the obtained speed setting value is used as the speed input value of the driver function module, which will not be repeated here.

[0056] It should be noted that the present invention provides a rapid alignment device for lesion targets and its control method, as well as a treatment bed, which determines whether a start signal input by a user is obtained; if so, controls the motor of the treatment bed to start; uses a timer set in the control module to record the duration of the user pressing the start button; and changes the movement speed of the treatment bed according to preset rules according to the duration of the user pressing the start button. It is achieved that not only the treatment bed can be moved at high speed from a distance from the laser center point to the vicinity of the isocenter, but also the lesion target can be smoothly aligned with the laser center point near the isocenter, which greatly reduces the alignment time before treatment.
